[0044] Reference Figure 4 The driving assembly 2 specifically includes: a driving chain 2-1, a chain connecting block 2-2 and a screw 2-3. The driving chain 2-1 is connected to an external driving mechanism. The driving chain 2-1 is set in a ring shape and is sleeved on two gears installed on the equipment bracket 1. The gears are driven to rotate by the external driving mechanism, thereby driving the driving chain 2-1 to perform circumferential motion. The chain connecting block 2-2 is fixedly connected to the outer ring of the driving chain 2-1, and a threaded hole is provided on the chain connecting block 2-2. The screw 2-3 is connected to the chain connecting block 2-2 through the threaded hole, and the screw 2-3 is located on the side of the chain connecting block 2-2 facing away from the driving chain 2-1. The screw 2-3 is connected to the rotating shaft assembly 3, and the circumferential reciprocating motion of the driving chain 2-1 drives the screw 2-3 to reciprocate along the moving direction of the driving chain 2-1. The reciprocating motion of the screw 2-3 drives the rotating shaft assembly 3 to rotate reciprocatingly. The rotation of the rotating shaft assembly 3 drives the program control box rotating shaft 5-1 to rotate, thereby controlling the program control box circuit switch.

[0045] Furthermore, the rotating shaft assembly 3 is installed perpendicular to the moving direction of the driving chain 2 - 1 .

[0046] Specifically, refer to Figure 5The rotating shaft assembly 3 includes a rotating shaft 3-1 and a shaft seat 3-3, and the rotating shaft 3-1 is fixed to the equipment bracket 1 through the shaft seat 3-3. A stopper 3-2 is sleeved on the rotating shaft 3-1, and the screw 2-3 of the driving assembly 2 is inserted into the stopper 3-2. The movement of the screw 2-3 drives the stopper 3-2 to rotate the rotating shaft 3-1; a connecting mechanism is also sleeved on the rotating shaft 3-1, and the connecting mechanism is located on a side away from the driving assembly 2, and the connecting mechanism is connected to the program control box 5.

[0047] As needed, two shaft seats 3-3 can be set, located on both sides of the block 3-2 respectively, and one of the shaft seats 3-3 is located at one end of the rotating shaft 3-1, fixed to the inner side of the annular drive chain 2-1, to support the rotating shaft 3-1.

[0048] Further, the stopper 3-2 is configured as a U-shaped groove 3-2-1, referring to Figure 6 The screw 2-3 of the driving component 2 is inserted into the U-shaped groove 3-2-1. When the screw 2-3 moves horizontally along with the driving chain 2-1, the stopper 3-2 will produce relative rotation due to the force of the screw 2-3. The stopper 3-2 will drive the rotating shaft 3-1 to rotate, thereby completing the process of the driving component 2 driving the rotating shaft component 3 to move.

[0049] In one embodiment, a stopper mounting seat 3-8 is sleeved on the rotating shaft 3-1, and two through holes are provided on the stopper mounting seat 3-8. The two through holes are symmetrically arranged with the rotating shaft 3-1 as the symmetry axis. The two side walls of the U-shaped groove are inserted into the through holes for fixed connection, and the screw 2-3 is inserted into the open end of the U-shaped groove 3-2-1.

A clamping structure is provided on the inner side of the connecting inner sleeve 3-6, which can clamp the rotating shaft 5-1 of the program control box. The rotating shaft 3-1 rotates, driving the connecting inner sleeve 3-6 to rotate. The rotation of the connecting inner sleeve 3-6 drives the rotating shaft 5-1 of the program control box to rotate, thereby realizing the switching of the program control box 5 circuit. In order to control the rotation angle of the connecting inner sleeve 3-6, a spring assembly 3-7 and a limiter on the connecting member 3-4 are also provided. One end of the spring assembly 3-7 is sleeved on the outside of the connecting inner sleeve 3-6, and the other end is fixed on the equipment bracket 1. The connecting member 3-4 is located on the rotating shaft 3-1 and close to the connecting inner sleeve 3-6. A limiter is provided on the connecting member 3-4. The limiter limits the rotation of the spring assembly 3-7, thereby limiting the rotation angle of the connecting inner sleeve 3-6.

[0051] Preferably, two of the limit members are symmetrically arranged, referring to Figure 7 The angle between the central axes of the two limit members is 90°, that is, the limit member can deflect 45° to the left and 45° to the right in the vertical direction of the spring assembly 3-7, so that the connecting inner sleeve 3-6 can rotate 90° and reciprocate within this 90°.

[0052] Preferably, the limiting member is configured as a limiting screw 3-5. It should be explained that the limiting member is not limited to the screw 3-5, but may also be other components, based on the ability to limit the spring assembly 3-7.

The program control box rotating shaft 5-1 passes through the front support 4-1 and is connected to the rotating shaft assembly 3. The rear end of the program control box 5 is fixed to the rear support 4-3.
